CREATE TABLE Orders (order_id INT, customer_id INT, product_id INT) uses customer_id and product_id, which is normalized.
Final Answer:
CREATE TABLE Orders (order_id INT, customer_id INT, product_id INT) -> Option A
Quick Check:
Normalized tables use IDs = CREATE TABLE Orders (order_id INT, customer_id INT, product_id INT) [OK]

Quick Trick: Normalized tables link by IDs, not repeated text [OK]
